I have a couple sets of 175W kits (electronic ballasts/mogul sockets/14,000K bulbs) that i ahve been trying to sell for $185 which is the cheapest ive been able to find and the same but in 250W kits for $200. I dont think he can do it for $100 unless he gets very crummy stuff (ie magnetic ballasts) with like 4,000K bulbs.
